(54) Transducer, electronic equipment and method of adjusting the frequency of the transducer


(57) A transducer (10) including a pair of oscillating reeds (1a, 1b) extending in the Y-direction for generating a first oscillation for generating a Coriolis force corresponding to the rotation of the transducer (10), a beam (2) extending in the X-direction and connected to the pair of oscillating reed (1a, 1b), a first detecting unit (6) provided on the beam (2) for detecting deformation of the beam (2) due to a second oscillation of the pair of oscillating reeds caused by the Coriolis force, a base member (5) for supporting the beam (2), a first connecting device (3) for connecting one end (2a) of the beam (2) and the base member (5), and a second connecting device (4) for connecting the other end of the beam (2) and the base member (5).
